## Writing Tests

Test structure:

```python
import pytest
from ccat_ops_db_api.transaction_buffering import SQLAlchemyTransactionBuilder

def test_transaction_builder():
    builder = SQLAlchemyTransactionBuilder(endpoint="test", site="test")

    step = builder.create(
        model_class=models.ExecutedObsUnit,
        data={"id": uuid.uuid4(), "status": "running"},
        step_id="test"
    )

    transaction = builder.build()
    assert len(transaction.steps) == 1
```
